Settings: Alert user when they attempt to add an invalid number to BL.

  - BlacklistProvider will reject numbers that aren't valid, silently. So instead of
  resuming to a blank screen, we should alert the user that the number they attempted to
  add is invalid by utilizing BlacklistUtils#addOrUpdate method.

Use actual storage type of sdcard/usb (2/2).

Currently, storage volume description for mount/unmount/format determined at
build time using PRODUCT_CHARACTERISTICS. For device which has only a sdcard or
only support usb storage, displayed description is correct. For device which has
both storage, the displayed description is totally wrong.

Use of actual storage type at runtime can eliminate the needed to specify
product characteristics, either default or nosdcard.
